NAME
       roar_vs_role - Update role for a stream
SYNOPSIS
       #include <roaraudio.h>
       int     roar_vs_role          (roar_vs_t * vss, int role, int * error);
DESCRIPTION
       This function updates the role of the stream.  This should be done before any read or write operation and
       can be used at any time to update the meta data.
PARAMETERS
       vss    The VS object to be updated.
       role   The new role of the stream.
       error  This  is  a pointer to a integer used to store the error value in case of error.  This can be NULL
              if not used but it is very recommended to use this error value to report good  error  messages  to
              the user.
RETURN VALUE
       On success these calls return 0.  On error, -1 is returned.
EXAMPLES
        struct roar_keyval kv[2] = {
         {.key = "TITLE",  .value = "Some title"},
         {.key = "ARTIST", .value = "Some artist"}
        };
        ret = roar_vs_meta(vss, &kv, 2, &err);
